The code:

    import std.range;
    void f(R)(R, void delegate(ElementType!R)) { }
    void main() { f([1], (int x) { }); }

gives:

    Error: template f does not match any function template declaration
    Error: template f(R) cannot deduce template function from argument types
!()(int[],void function(int x) pure nothrow @safe)


but it should obviously be able to infer the types...
